MICHEL STANISLAUS YASSUKOVITCH, OF NEW YORK, N. Y.

ADJUSTABLE EYEGLASSES.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed July 24, 1918. Serial No. 246.505,

To all whom it may concern:

Be it known that I, MICHEL STAxisnaUs Yassoxovrrcn, a Russian subject. residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in .\dj ustable Ilyeglasses: and I do hereby declare he following to be a full, clear, and exact description of the invention, such as will on able others skilled in the art to which it appertains to make and use the same. i My present invention relates to improvements in adjustable eyeglasses, and it is in-' tended to provide an arrangement which may be supported on the upper portion of the head of the wearer, without pinching the nose or irritating the ears of the wearer; and in which the eyeglasses may be safely held in place without any possible danger of their dropping off while in use.

My invention is intended more particularly for-"shop or ofiiee use, where it is necessary to use the eyes continuously and where. the glasses as ordinarily constructed are apt to either. give discomfort, or are liable to fall off.

According to my invention I combine safety for the glasses and comfort to the wearer.

My invention will be more fully understood after reference to the accompanying drawings, in which like parts are indicated by similarreference symbols throughout the several views, and in which:

Figural shows the complete apparatus as in use by the wearer.

Fig. 2 is a rear view of the apparatus as detached from the head of the wearer, with the head band broken away.

Fig; 3 is a side elevation of the complete. apparatus, with the head band broken away.

Fig. 4 shows a section along the line -l--t of Fig. 1 of the frame and head band, the glasses being omitted.

Fig. 5 is a view on a larger scale of a portion of one of the glasses and its supporting arm, parts being broken away.

Fig. 6 is a detail showing the free end of the head band, with the guide attachment.

connected thereto; and

Fig. 7 shows the complete apparatus folded up in a case, the case being shown as open,

A represents the main frame made of sheet metal, sutliciently flexible to fit snugly to the headof the wearer when in use. This main frame is provided with guide slots 1:

and (/{tlirough which passes the head band ll and the ends of this frame are turned outward as at (L: and n.

The head band 13 is rove double through these guide slots (1. and u, as shown in Fig. 4, and one end I) of the head band is then attached to the main frame, as at u. see Fig. 4, while the other end carries the guide piece I) having outwardly projecting guide lugs L as shown in Figs. -l and (3. This head band is made of resilient metal. preferably steel, plated with nickel or other metal that will not oxidize and will not stain the head of the wearer.

The guide lugs I) serve also as a convenicnt handle by means of which the head band may be adjusted to the 'head of the wearer.

Projecting from the lower edge of the head band I provide two lugs A with parallel outer ends a, forming a bracket between which outer ends the arcuate member is adjustably held as by means of the clamp screw I) and the pin (1 which projects through the slot in the arcuate member (J.

supporting post I), and the joint between the.

two should be stiff enough so that this supporting post will remain in the position at which it is set.

Fast to the lower end of the supporting post E is the bent shaft F, having two divergent arms f on which arms the. locking blocks (i are fast. Each of these blocks has a tongue or catch adapted to en age in one or the other of the. notches h which are provided on opposite sides of the block H carrying the eyeglass rim.

'lhe eyeglass-rim I is shown as provided with'a lug i engaging in a socket in the block II, and secured thereto by means of the set screw h. The block II. is normally snapped to 'theengaging position with the blocks G by means of the coil spring mounted .on the arms f and held in place by I down to the'initial position.

is to be used. The lenses are then adjusted to the proper position vit-h'regard to the line of sight of each eye, y turning the lug i in its socket and clamping the same by means of the clamp screw 72. The position of the glasses vertically, as also the distance of the glasses from the eyes, may be adjusted by easing up on the clamp screw D and setting the arcuate member C to the proper position.

It will only be necessary to make these various adjustments once for the same person, after which the parts will ordinarily remain in adjustment.

The complete apparatus may be fitted to the head of the wearer bymoving the free end of the head band in or out.

It will be noted that the complete apparatus comprises a main frame and a head band for securing the same to the head of the wearer, and a secondary frame adjustably connected to the main frame and carry;- ing the eyeglasses If desired, the apparatus may be hung up at the oflice or workshop in the adjusted pos1 tion, but if desired to carry the same about, the same may be put into the position shown in Fig. 7'and inclosed in a suitable case.

I have designed such a case, indicated by M-in Fig. 7, in which the bottom m is rounded and the top is open, having parallel sides m", which open top may be closed by means of hinged covers M" and M The hinged cover M is preferably provided with. anges m to engage the sides of the case, and the hinged cover M is provided with similaroflanges m and with a transverse flange m which passes over the free end of the cover M and forms a tight box.

In order to arrange the parts for assembling in the case, ease up on the clamp screw D, swing the glasses inward to the, position shown in dotted lines in Fig. 3, draw in the free end of. the head band and fold the parts in the position shown in Fig. 7

When desired the complete apparatus may be readily removed from the case and the parts restored to the initial position shown in Fig. 1. I

It will be obvious that if desired to use the eyeglasses for one eyeonly, the'o'ther eyeglass may be entirely omitted, or itmay be swung forward and upward until the notch it engages with the latch 7, when that particular lens will be held out of the line of sight. Itmay be promptly restored to the line of sight again by swinging'the same While I have illustrated and described the apparatus in what I belie e to be the preferred form, itwill be obvious thatvarious.

' modifications might be made in the construction, combination and arrangement of parts which cou1d be used without departing from the spirit of my invention.
